Guidance on Safe Use
Administrative data
First-aid measures
Eye: Eye irritation. Flush immediately with large amounts of water for at least 15 minutes. Eyelids should be held away from the eyeball to ensure thorough rinsing. If irritation persists get medical assistance.
Skin: Itching or burning of the skin. Immediately flush the skin with plenty of water while removing contaminated clothing and shoes. If irritation persists get medical attention. Wash contaminated clothing before reuse.
Inhalation: Remove exposed person from exposure areas to fresh air immediately.
Ingestion: If victim is conscious, immediately give 2 to 4 glasses of water and induce vomiting by touching fingers to back of throat. Get immediate medical attention.
Fire-fighting measures
Suitable Extinguishing Media: Use dry chemical, foam, or carbon dioxide to extinguish fire. Water may be ineffective but should be used to cool fire-exposed containers, structures and to protect personnel. Use water to dilute spills and to flush them away from sources of ignition.
Fire Fighting Procedures:. Exposed firefighters must wear NIOSH-approved positive pressure self-contained breathing apparatus with full-face mask and full protective clothing. Cool down the containers and equipments exposed to heat with a water spray.
Unusual Fire and Explosion Hazards: No acute hazard. Avoid breathing vapors or dust.
Combustion Products: Irritating or toxic substances may be emitted upon thermal decomposition. Thermal decomposition products may include potassium oxides and iodine vapour.
Accidental release measures
Avoid contact with skin and eyes. Do not breath dust. (Also see exposure control).
Sweep up or vacuum up the spilled product. Collect the product and place it in a suitable (e.g. plastic) container.
Avoid generating dust. Wash spill area with water.
Do not flush to sewer or waterways. Prevent release to the environment if possible. Refer to Section 15 for spill/release reporting information.
For disposal of residues refer to Section disposal consideration.
Handling and storage
Handling: Avoid contact with eyes, skin or clothing. Avoid generating dust. Do not breathe dust. Keep container closed. Use in a well ventilated area. Use good personal hygiene practices. Wash hands before eating, drinking, smoking. Remove contaminated clothing and clean before re-use.
Storage: Store in the original closed containers secure from children, pets or livestock. Store away from sunlight and moisture. Store away from oxidizers. Empty containers may contain residue. Do not cut, grind, drill, or weld on or near containers unless precautions are taken against these hazards.

Exposure controls / personal protection
Engineering Controls: Local exhaust or general dilution ventilation should be in the facility. Provide
mechanical ventilation for confined spaces. Safety shower and eyewash should be in the facility.
Personal Protective Equipment:
Eye Protection: Wear chemical safety goggles and face shield. Have eye-wash stations available where eye contact can occur.
Skin Protection: Avoid skin contact. Wear appropriate protective and garments to prevent bodily contact.. Recommended protective materials include: PVC, Butyl, Neopren and Viton rubber.
Respiratory Protection: High efficiency particulate respirator should be used. Respiratory protection must be provided in accordance with OSHA 29 CFR 1910.134 or EC 89/686/EEC.
Stability and reactivity
Stability : Stable under normal conditions of use. Protect from moisture and sunlight.
Incompatibility: Incompatible with oxidizers, metals and strong acids.
Hazardous Reactions/Decomposition Products: Oxidation products may include iodine fumes, hydrogen iodide and potassium oxides.
Disposal considerations
Waste Classification: Non-hazardous
Disposal Methods: Recycle or dispose in a chemical landfill in accordance with all local, state or federal regulations. Dispose of packaging in an authorised facility.
